During a complete bike overhaul all the components are removed, the frame is cleaned and the threads are checked and chased (if necessary). Then the Headset, hubs & bottom bracket are overhauled, cleaned, adjusted, re-lubed & reinstalled. New Cables and Housing are installed. The brakes and derailleurs are adjusted and the pulleys are lubed. Wheels are trued (lateral, round and tension), drivetrain is cleaned lubed and adjusted and all nuts and bolts are checked.
